What does an Apdex rating indicate in application performance monitoring?

An Apdex rating serves as a standard measurement to gauge user satisfaction based on the response times of an application. This metric provides insight into how well an application meets user expectations regarding performance. It categorizes the user experience into three levels: satisfied, tolerating, and frustrated, depending on the response time thresholds set for the application. Thus, a higher Apdex score indicates that more users experienced satisfactory performance, which directly correlates to overall user satisfaction with response times. The Apdex rating effectively helps organizations understand the impact of application performance on user engagement and satisfaction.
